I-calcium lignosulfonate i-arhente yokunciphisa amanzi itsalwa kulwelo lwenkunkuma yepulp. Iimveliso zahlulwe zibe ngamacandelo amabini, ezizezi calcium ityuwa kunye netyuwa sodiumlignosulfonate, le yokugqibela ifunyenwe kwiprosesa yangaphambili. Ekwenziweni kwerayon okanye kushishino lwephepha, xa iinkuni ziphekwe kwiqondo lobushushu eliphezulu kunye noxinzelelo oluphezulu, i-sulfite yongezwa ukwahlula i-cellulose kunye ne-non-fiber emthini, kwaye i-cellulose efunyenweyo yinto ekrwada ye-rayon, eyenziweyo. uboya, iphepha, njl njl. I-non-cellulose echithwe kwisisombululo yayilawulwalignosulfonates kunye nentwana yeswekile.
Esi sisombululo sibizwa ngokuba yinkunkuma yepulp. Emva kokuba utywala kunye negwele zikhutshiwe kulwelo olulahlwayo, izinto eziseleyo ke zitshizwe ngomoya oshushu zenze umgubo omdaka.calcium lignosulfonateumgubo. Umxholo wecalcium lignosulfonatemalunga ne-45-50%, ukunciphisa izinto Umxholo ungaphantsi kwe-12%.
Okwangoku, imfuno yemarike yecalcium lignosulphonakwaye iimveliso zayo ezilungisiweyo zikhula ngokuthe ngcembe, ukwenza uhlalutyo kunye nokusetyenziswa kwe-lignin kunye nokufumana inzuzo yezoqoqosho ehambelana nayo ngokuthe ngcembe ibe yinyani. Ke ngoko, kwixesha elizayo, siya kuqinisa uphando kunye nophuhliso lweendlela ezintsha, itekhnoloji entsha kunye neenkqubo ezintsha kuhlaziyo.calcium lignosulphonaukuphuhlisa iimveliso ze-lignin ezinemfuno enkulu yemarike, ukusebenza kakuhle kunye neenzuzo ezilungileyo zoqoqosho, kunye nokukhawulezisa ukusetyenziswa okukhulu kwe-lignin. Iya kukhuthaza ukusetyenziswa ngokupheleleyo kwemithombo yendalo ehlaziyekayo kunye nolawulo olusisiseko lokucocwa nokulahlwa kolwelo lwenkunkuma yephepha.
Lignosulfonatei-arhente yokunciphisa amanzi isetyenziswe kwilizwe lam iminyaka engama-40-50. Nangona kunjalo, ngenxa yezinga eliphantsi lokunciphisa amanzi, ukuseta okucothayo, ukunyuka okuncinci kumandla oxinzelelo lwekhonkrithi, kunye namandla aphantsi okuqala, ukusetyenziswa kwayo kwikhonkrithi kulinganiselwe. Ikwachaphazela nokuphuculwa kwexabiso layo. Ngoku, calcium lignosulfonatei-arhente yonciphiso lwamanzi isasetyenziswa ikakhulu kulwakhiwo lwekhonkrithi yasehlotyeni njengesicuphisi sekhonkrithi. Ihlabathi linokuvelisa i-30 yezigidi zeetoni ze-lignin yemizi-mveliso minyaka le. Okwangoku, kuphela malunga ne-6% ye-industrial lignin kwilizwe lam esetyenziswayo, kwaye uninzi lwabanye lukhutshelwa emilanjeni njengenkunkuma. Ungcolise ngokunzulu okusingqongileyo.
Ukuvuselela kunye nokuguqulacalcium lignosulfonatekunye nokuyidibanisa ne-naphthalene-based superplasticizer inokwenza ugcino lokunciphisa amanzi ngobuchule obuphezulu, kwaye boyise ukusilelaicalcium lignosulfonate ukulibaziseka kunye namandla aphantsi kwangoko, kunye nokunciphisa kakhulu i-naphthalene-based superplasticizer. iindleko kunye nokwandisa ububanzi bokusetyenziswa kwe-calcium yomthi.
